DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Embodiments of the present disclosure are described in detail below, and the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

The video content pushing method, apparatus, electronic device, and storage medium of the embodiments of the present disclosure are described below with reference to the drawings.

Currently, applications with video recommendation services may collect historical playing data of users to implement personalized video recommendations based on user preferences. In actual applications, it may occur a failure of the video recommendation service. Therefore, when the video recommendation service fails, a primary disaster recovery system may be activated to continue to push current popular videos to the application client, thereby ensuring the user experience. For example, it may respectively store the video ID (identifier) of the current popular video through redis and itemlist, and then obtain the popular video according to the video ID and push it to the application client.

However, since a primary disaster recovery system depends on services such as itemlist and redis, when the itemlist and redis themselves fail, the primary disaster recovery system cannot obtain popular videos for pushing. Therefore, the method for pushing a video content of the embodiment of the present disclosure may activate a standby disaster recovery system when the primary disaster recovery system of the video recommendation service is failure, and push the video content to the application client through the standby disaster recovery system.

FIG. 1 is a schematic flowchart of a method for pushing the video content according to an embodiment of the present disclosure. As shown in FIG. 1, the method for pushing video content includes the following steps.

Step 101: when the primary disaster recovery system of the video recommendation service fails, the standby disaster recovery system is activated. The primary disaster recovery system pushes the current popular video to the application client after the video recommendation service fails.

In the embodiment of the present disclosure, it may first detect whether the primary disaster recovery system fails before activating a standby disaster recovery system. When the primary disaster recovery system of the video recommendation service fails, the standby disaster recovery system is activated.

For example, it may detect whether the itemlist service fails, and then determine that the primary disaster recovery system occurs when the itemlist service fails, and activate the standby disaster recovery system.

In an embodiment of the present disclosure, when it is known that the primary disaster recovery system of the video recommendation service is normal, the current popular video may be pushed to the application client through the primary disaster recovery system. For example, it may respectively store the video ID (identifier) of the current popular video through redis and itemlist, and then obtain the popular video according to the video ID and push it to the application client.

Step 102: a video access request sent by an application client is received, and a first historical video content stored in a middleware is invoked, which is obtained at a preset ratio from historical recommendation videos of the video recommendation service.

In an embodiment of the present disclosure, when the server pushes videos to all users, the server may store the pushed recommendation video request result in the middleware at the preset ratio in real time. Furthermore, when receiving the video access request sent by the application client, the server may invoke the recommended video request result stored in the middleware.

For example, 1% of the video contents may be selected from the historical recommended videos to store in the middleware as the first historical video content. Furthermore, when receiving the video access request sent by the application client, the first historical video content is invoked from the middleware.

The first video content may be selected from all historical recommended videos, or randomly selected from historical recommended videos recommended to others.

As an example, the middleware may be a middleware server, and the first historical video content may be a uniform resource locator (URL) of the video.

The preset ratio may be obtained based on a large amount of experimental data, or may be set according to actual needs, which is not limited herein.

Step 103: the first historical video content is pushed to the application client for playback.

In this embodiment, since the first historical video content stored in the middleware has been obtained, the first historical video content may be directly pushed to the application client for playback.

As an example, it may randomly select one or more of the first historical video contents and push it/them to the application client for playback at the application client.

As another example, the first historical video content may also be scored according to a preset algorithm, and then the video content with the highest score is selected to be pushed to the application client for playback.

It should be noted that the above manner of pushing contents to the application client is only exemplary, and texts, pictures, and other forms of contents may also be pushed in addition to video contents, which are not limited herein.

In this embodiment, after the standby disaster recovery system is activated, the historical video contents stored in the middleware may be directly invoked, which realizes that the result of returning files is directly read at the middleware layer, and in the case of other services breakdown or failure, the historical video content may also be obtained and pushed, thus the dependence of disaster recovery on other services is eliminated so that the disaster recovery solution is more robust and the stability of pushing video contents is proved.

In summary, according to the method for pushing a video content of the embodiment of the present disclosure, when it knows that a primary disaster recovery system of a video recommendation service fails, a standby disaster recovery system is activated; a video access request sent by an application client is received; a first historical video content stored in a middleware is invoked, Which is obtained at a preset ratio from historical recommendation videos of the video recommendation service; and the first historical video content is pushed to the application client for playback. Therefore, the dependence of the disaster recovery on other services is eliminated, so that the disaster recovery solution is more robust, and the stability of pushing the video contents is improved.

Based on the above embodiment, the method for pushing a video content of the embodiment of the present disclosure may further deduplicate the pushed video contents to avoid repeated pushing.

FIG. 2 is a schematic flowchart of another method for pushing a video content according to an embodiment of the present disclosure. As shown in FIG. 2, after the first historical video content is pushed to an application client for playback, the method for pushing a video content further includes the following steps.

Step 201: a corresponding relationship between a first video identifier of the first historical video content and a user identifier of the application client is recorded.

In an embodiment of the present disclosure, when the server receives the video access request sent by the application client, the server may obtain the user identifier of the application client and store it in the middleware. Furthermore, after the first historical video content is pushed to the application client, the first video identifier of the pushed first historical video content is obtained, and a corresponding relationship between the first video identifier and the user identifier is stored in the database.

The forms of the first video identifier and the user identifier include but are not limited to digital format, text format, and the like.

Step 202: After the video recommendation service or the primary disaster recovery system is recovered, the video contents to be pushed to the application client are filtered based on the first video identifier.

In an embodiment of the present disclosure, after the video recommendation service or the primary disaster recovery system is recovered, the user ID corresponding to the application client may be obtained when pushing video contents, and then the video contents to be recommended are filtered based on the first video ID corresponding to the user ID.

As an example, the user identifier is a, the corresponding first video identifier is A, and the video identifiers corresponding to the video to be recommended are A, B, and C, respectively, and then the first video identifier is matched with the video identifier of the video to be recommended. It is determined that the video A is the video that has been pushed, so the video A is deduplicated, and the videos B and C are pushed to the application client corresponding to the user identifier a.

It can be understood that after the video recommendation service or the primary disaster recovery system is recovered, the video that has been pushed by the standby disaster recovery system may be repeatedly pushed when the primary disaster recovery system pushes the videos. Therefore, when a service such as userinfo for obtaining a user ID operates normally, the server may obtain the user ID corresponding to the application client. Furthermore, by obtaining the corresponding relationship between the first video ID and the user ID, after the video recommendation service or the primary disaster recovery system is recovered, the video deduplication process may be performed when pushing videos to the application client corresponding to the user ID, so as to avoid pushing duplicate videos.

According to the method for pushing a video content of the embodiment of the present disclosure, after the video recommendation service or the primary disaster recovery system is recovered, the pushed video contents may be duplicated according to the first video identifier, thereby to avoid pushing duplicate videos and to improve user stickiness to the product.

Based on the above embodiment, when the video content module operates normally, the video identifier may also be obtained from a local file to obtain historical video content according to the video identifier for pushing.

FIG. 3 is a schematic flowchart of another method for pushing a video content according to an embodiment of the present disclosure. As shown in FIG. 3, before the invoking the first historical video content stored in the middleware and obtained at the preset ratio from historical recommendation videos of the video recommendation service, the method for pushing a video content also includes the following steps.

Step 301: whether a video content module fails is detected.

As an example, it may detect whether the item service (the service that obtains video information) fails, and then determine that the video content module occurs when the item service fails.

In an embodiment of the present disclosure, when the video content module fails and the video content cannot be obtained according to the video identifier, a first interface of the standby disaster recovery system associated with the middleware is activated, and then the first historical video content stored in the middleware is invoked, and the first historical video content is pushed to the application client for playback.

Step 302, when the video content module works normally, a second interface of the standby disaster recovery system associated with the local file is activated.

The local file is a file stored locally on the server.

Step 303: a second video identifier stored in the local file is invoked and obtained at a preset ratio from historical recommendation videos of the video recommendation service.

In an embodiment of the present disclosure, when the server pushes videos to all users, the second video identifier of the pushed recommended video may be stored locally on the server at a preset ratio. Furthermore, after activating the second interface of the standby disaster recovery system, the second video identifier stored locally by the server may be invoked.

The preset ratio may be obtained based on a large amount of experimental data, or may be set according to actual needs. The forms of the second video identifier include but are not limited to digital forms, text forms, etc., which are not limited herein.

Step 304: a second historical video content corresponding to the second video identifier is obtained from the video content module; and the second historical video content is sent to the application client.

As an example, the corresponding relationship between the video ID and the historical video content and the historical video content may be stored in the video content module in advance, and after the second video ID is obtained, it may obtain the corresponding second historical video content by querying the corresponding relationship in the video content module and send it to the application client.

In this embodiment, when the primary disaster recovery system fails, if the video content module operates normally, such as the case where the redis fails but the item operates normally, the corresponding historical video content may also be obtained according to the video identifier stored in the local file to be pushed to the application client. Moreover, since the second interface of the standby disaster recovery system obtains the historical video content through an API (application programming interface), it may generate advertising results and increase advertising revenue.

The following describes situation with the recovery of the video recommendation service failure.

FIG. 4 is a schematic flowchart of another method for pushing a video content according to an embodiment of the present disclosure. As shown in FIG. 4, the method for pushing a video content includes the following steps.

Step 401, the primary disaster recovery system and the standby disaster recovery system are disactivated when the video recommendation service is recovered.

As a possible implementation, it is possible to detect whether the video recommendation service operates normally in real time, and when the video recommendation service operates normally, the primary disaster recovery system and the standby disaster recovery system are disactivated.

Step 402: it may receive a video access request sent by the application client to obtain a third video identifier corresponding to a user preference feature of the application client.

In an embodiment of the present disclosure, the user preference feature may be generated based on data such as the user's click preference, video category, and viewing time when browsing the video. Furthermore, when the application client requests the video, the user preference feature is carried in the video access request and sent to the server. The server filters the video to be pushed according to the user preference feature and obtains the third video identifier corresponding to the video that matches the user preference feature.

For example, when the user preference feature is a movie video, the server obtains the video identifier of the movie video from the videos to be pushed as the third video identifier.

The form of the third video identifier includes but is not limited to a text form, a digital form, and the like.

In an embodiment of the present disclosure, the video to be pushed may also be deduplicated according to the user identifier, of which the implementation manner is similar to that in the foregoing embodiment, and the details are not described herein again.

Step 403: a third video content corresponding to the third video identifier is obtained from the video content module; and the third video content is sent to the application client.

As an example, the corresponding relationship between the video ID and the historical video content and the historical video content may be stored in the video content module in advance, and after the third video ID is obtained, it may obtain the corresponding third historical video content by querying the corresponding relationship in the video content module, and send it to the application client. As a result, the videos are pushed according to user preferences, thereby improving the personalization of video pushing.

The following describes the actual application process.

Referring to FIG. 5, it may first detect whether the video recommendation service fails, and when the video recommendation service works normally, the videos are pushed through the video recommendation service. Furthermore, when the video recommendation service fails, the primary disaster recovery system pushes the videos. For example, the primary disaster recovery system may respectively store the video ID of the current popular video through the redis and itemlist, and then obtain the popular video according to the video ID and push it to the application client.

Further, when the primary disaster recovery system fails, the standby disaster recovery system is activated. It may first detect whether the video content module fails, and when the video content module works normally, the video identifier in the local file is obtained through the second interface of the standby disaster recovery system, and then the video content is obtained according to the video identifier for being pushed. When the video content module fails, the video content stored in the middleware is invoked and pushed through the first interface of the standby disaster recovery system. In addition, after pushing the video content, the user ID and the corresponding video ID may also be obtained to facilitate deduplication when the video recommendation service or the primary disaster recovery system is recovered, so as to avoid pushing duplicated contents. As a result, the dependence of disaster recovery on other services is eliminated, so that the disaster recovery solution is more robust, and the stability of pushing video contents is improved.

In order to implement the above embodiments, the present disclosure also proposes an apparatus for pushing a video content.

 7. A non-transitory computer-readable storage medium comprising a computer program operable to, when executed by a processor, implement the method for pushing a video content, the method comprising: activating a standby disaster recovery system when a primary disaster recovery system of a video recommendation service fails; receiving a video access request sent by an application client, and invoking a first historical video content stored in a middleware and obtained at a preset ratio from historical recommendation videos of the video recommendation service; and pushing the first historical video content to the application client for playback.
 8. The electronic device of claim 6, wherein the programs further comprise executable codes for: recording a corresponding relationship between a first video identifier of the first historical video content and a user identifier of the application client; and filtering video contents to be pushed to the application client based on the first video identifier after the video recommendation service or the primary disaster recovery system is recovered.
 9. The electronic device of claim 6, wherein the programs further comprise executable codes for: detecting whether a video content module fails; and activating a first interface of the standby disaster recovery system associated with the middleware when the video content module fails; and wherein the invoking the first historical video content comprises: invoking the first historical video content stored in the middleware and obtained at the preset ratio from historical recommendation videos of the video recommendation service by using the first interface of the standby disaster recovery system.
 10. The electronic device of claim 9, wherein the programs further comprise executable codes for: activating a second interface of the standby disaster recovery system associated with a local file when the video content module operates normally; invoking a second video identifier stored in the local file and obtained at a preset ratio from historical recommendation videos of the video recommendation service by using a second interface of the standby disaster recovery system; obtaining a second historical video content corresponding to the second video identifier from the video content module; and sending the second historical video content to the application client.
 11. The electronic device of claim 9, wherein the programs further comprise executable codes for: disactivating the primary disaster recovery system and the standby disaster recovery system when the video recommendation service is recovered; receiving a video access request sent by the application client, and obtaining a third video identifier corresponding to a user preference feature of the application client; and obtaining a third video content corresponding to the third video identifier from the video content module, and sending the third video content to the application client.
